CEM ENTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 588,517, dated August17, 1897.

Application led November 16, 1896. `Serial No. 612,314. (No model.) i Y1 T0 all whom, 7175 710,0,7/ concern.'

'new and useful Improvements in Cementing Devices, of which thefollowing is a specilication.

This invention has for its object to produce a device for coating theend of a cane strip with glue for securing to the end of another strip;and it consistsof a gluing device having those features of constructionand arrangement which are illustrated on the drawin gs, and which Ishall now proceed to describe in detail and then point ont in the claimshereto appended.

Reference is to be had to the accompanying drawings, and to the lettersand figures marked thereon, forming a part of this speciflcation, thesame letters and igures designating the' same parts or features, as thecase may be, wherever they occur.

Of the drawings, Figure l is a side elevation of a device embodying myinvention.

'.Fig. 2 is an enlarged section of the same on the line 2 2 of Fig. l.Fig. 3 shows a strip of cane having a wedge-shaped end coated with glueby my device. Fig. et illu strates the manner ofsecuring the two stripsof cane together by gluing the wedge-shaped end of one between the splitportions of the end of the other.

In carrying out my invention I employ an ordinary supporting-bracket a,having a depending arm b and secured to an upright or standard c, risingfrom a work-bench or other base d.

The bracket is formed with a recess, so as to provide two arms a d2, towhich is secured a metallic cylindrical receptacle e by means of screwsa3 or in any other convenient inanner. The receptacle has a top cap e',secured thereon by screws e2, passed through the edge of thecap intostuds e3, projecting ont from the periphery of the receptacle, the caphaving an apertured boss e4,into which is threaded the nozzle f of anair-pump.

' For the sake of illustration I have shown an ordinary cylindricalpump, such as employed in inflating the pneumatic tires ofbicycle-wheels, it having a reciprocatory valved cylinder f and astationary piston (not shown) v connected to the handles f2.

The nozzle f is provided with a valve f3, so that when air has beenforced into the receptacle the valve may be shut ott, so as to preventits escape. Y

The lower end of the receptacle is provided with a head f4, suitablysecured therein, as by sweating, and has an outlet f5, on which isthreaded a nozzle g, having a valve g and a lower externally-threadedend. To the said threaded end is screwed a tip g2, which has a flatbottom surface with a small number of minute perforations gi.

To the extreme lower end of the arm b is pivoted a forwardly-extendinghandle h, having a tlat enlargementh, located directly under thetip,`upon which enlargement is secured a flat washer h2 of leather orother suitable material, by means of a screw h3 or by any othervsuitable means. The washer is pressed against the flat surface of thetip g2, so as to close the apertures g3, by a spring t', having one endattached to an eye e" of the handle and the other end at i2 to the upperend of the arm b.

VA suitable quantity of liquid glue or cement, preferably of a kind thatwill set or harden quickly, is placed in the receptacle and the valve g`is turned so as to allow it to run down through the nozzle g into theperforated tip, it peing prevented from passing through the perforationsby the pressure of` the washer h2. Then the upper part of the receptacleis filled with compressed air until the pressure on the glue or cementis sufficient to cause it to tlow freely through the minute perforationswhen the handle is depressed so as to move the washer away from them.The device is then ready for use. A number of canes having beenpreviously prepared by cutting one end of each wedge-shaped, as at 2,and by splitting the other end, as at 4c 4, the wedge-shaped end of oneis yplaced between the washer and the delivery-tip, the handle havingbeen previously depressed to permit this. The cement or glue oozesthrough the minute perfor-ations as soon as the handle is depressed, sothat the end of the cane is coated, and the 'surplus glue is wiped oi bydrawing the cane from between the washer and the tip. Then the coatedend is quickly inserted between the split halves of the end of anothercane, as shown in Fig. 4, and the said halves are pressed against it, soas to cement them iirmly together. As soon as the pressure of air isreduced by the withdrawal of the glue or cement the pressure isincreasedby means of the air-pump to the desired extent.

Vhen the device is not in use, the valve g', through the nozzle, may beclosed, so as to shut o the glue.

My invention is not limited to the details of construction hereinbeforedescribed, as it may be embodied in devices constructed in other ways.For instance, while it is desirable for obvious reasons to force theglue or cement through the tip by air-pressure, yet I have contemplatedproducing the pressure by other means, as by a weighted piston, and, ifdesired, the minute quantitiesof glue may be fed to the cane through asponge instead of through perforations in the tip, since the only objectof employing the perforated tip is to secure the liow of a smallquantity of the glue, and any other device for securing the same resultmay be used in its stead thereof.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though Without attempting to set forthal1 of the forms in which it may be made or all of the modes of its use,I declare that what I claim isl. A device of the character described,comprisinga receptacle to contain the liquid glue, means for deliveringthe glue from the same in minute quantities, a depressible device forcutting off the delivery of the glue and means for regulating the iiowof glue to the delivering means.

2. A device of the character described, comprisin ga receptacle tocontain the liquid glue, means for delivering the glue from the same inminute quantities, and a spring-held wiper for cutting off the deliveryof the glue,`said delivering means and said Wiper being constructed andarranged to coat with glue both sides of an article inserted betweenthem.

3. A device of the characterdescribed, comprisin g astationarily-snpported receptacle to contain the liquid glue, a nozzleleading from the same and having a delivery-tip, means for regulatingthe iiow of glue through said nozzle and yielding means for closing saidtip, said yielding means consisting of a pivotcd spring-held bar.

Ll. Adevice of the characterdescribed, colnprisinga receptacle tocontain the liquid glue, a nozzle leading from the same and having adelivery-tip, means for regulating the {iow of glue through said nozzleand a depressible handle having a washer for closing said dclivery-tip.

5. Adevice of the characterdescribed, comprising a stationarily-mountedreceptacle to contain the liquid glue, a nozzle having a delivery-tip, acut-ott valve in said nozzle, a yielding fiat wiper arranged below thetip to receive between it and the nozzle the end of a cane and means formoving the wiper away from the said tip.

6. A device of the characterdescribed, com'- prising astationarilymounted receptacle, adapted to contain a quantity of glue, areduced delivery-nozzle projecting downward from said receptacle andhaving a fiat tip, means for varying the iiow of glue through saidnozzle, a fiat wiper held yieldingly against the fiat tip so as to beconstantly coated with glue, and a pivoted handle for depressing saidwiper.

7. A device of the character described comprising a closed casing tocontain glue, a delivery-nozzle leading from said receptacle, means forregulating the iiow of glue through said nozzle, yielding means forclosing said nozzle, and means for maintaining a pressure upon the bodyof glue.

8. A device' of the character described comprising a closed casing tocontain glue, a delivery-nozzle leading from said receptacle, yieldingmeans for closing said nozzle, and an air-pump attached to the cylinderfor maintaining the body of glue under a continuous pressure.

9. Adevice of the character described, comprising an air-tightreceptacle to contain the glue, an air-pump for maintaining a pressureof air upon the glue, a delivery-nozzle having a iiat tip with minuteperforations, means for regulating the flow of glue through said nozzle,and a yielding wiper normally pressed against the tip to close theperforations.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 27th day of October, A. D.1896.
